Title: Top provided with means for the production of sparks by means of pieces of cerium iron
IPC: A63H33/36
Filed: 1928-04-11
Abstract: 301,791. Marklin et Cie Ges., Geb. Dec. 5, 1927, [Convention date]. Tops; spark-producing toys.-A top, in which sparks are produced by pieces of cerium iron rubbing against a frictional surface, is constructed so that the frictional surface is secured to the body of the top while the pieces of cerium iron are arranged to slide in recesses in a vane member loose on the axle of the top and formed with air brake surfaces. To the axle a is connected an upper plate b with apertures p through which the sparks may be viewed. Against a stepped portion c of the axle are pressed by a nut e a disc d, the friction disc f and a plate g. The pieces of cerium iron k are contained in guide channels i on the vane member h. The guide channels are inclined outwards, so that the centrifugal force presses the cerium iron onto the disc, and they are of such a size as to allow the cerium iron to slide up and down and to revolve freely within them. The friction disc f and the pieces of cerium iron k can readily be replaced by removal of the nut e and lower plate g.

Abstract: 1,075,133. Work benches. CONTROLS & SWITCHGEAR Ltd. March 8, 1965 [March 13, 1964], No. 10825/64. Heading B4X. A workman's bench structure in the form of a cabinet comprises a fixed portion 10 having a fixed working top 13, a shelf 17 and trays 15, 16 which form in part the side walls of the bench, and a laterally movable part 11 including a side wall 18 of the cabinet which is slidable from a retracted to an extended position and is provided with tray-like containers in the form of drawers 21, 22. A movable working top 20 for the movable part 11 has a mounting on the movable portion which allows it to pivot through 270 degrees from its horizontal position of use to a position flat against the vertical side 18. The portion 11 is provided with a small flanged wheel (24) which can run upon a rail on the ground. The rail when not in use is stored in an inverted channel (25) in the fixed portion 10. The mounting for the working top 20 is slidable on guides fixed to the end wall 18 thus rendering the surface 20 adjustable in height. The member 20 may be completely removed from the stand and refitted at any one of a number of positions at the base of the bench to form a stand or stored flat against either end wall 18. An additional working surface (30), Fig. 2 (not shown), comprises a tool tray slotted into the left-hand end of the fixed portion 10. Means for looking the portions 10, 11 in retracted position are described with reference to Fig. 4 (not shown). A pipe vice may be stored in the upper drawer of the movable portion 11 and hinged to the end wall 18 so as to be swingable into working position. Attachment shackles may be provided for crane lifting gear or hinged handles or carrying bars for'manual operation.

Title: Improvements in or relating to variable speed gears
IPC: F16H9/10
Filed: 1941-08-27
Abstract: 551,690. Variable-speed gearing. BOOTH. A., and COLES, F. H. Aug. 27, 1941, No. 10907. [Classes 80 (i) and 80 (ii)] A variable-speed gearing embodies a pair of expanding pulleys connected by an endless driving member. Each pulley has two parts 1, 2 with conical faces having radial slots 8. Each opposite pair of slots 8 accommodate a slide 9 having guiding rollers 10, and a compartment 12 containing a pack of thin plates 13. Radial movement of the plates 13 is limited by a pin 14 and slot 15. The plates 13 are supported against inward movement by a mass of small steel balls 16. The driving member comprises a belt or chain. It has taper sides 21 to engage the conical sides of the pulleys, and inwardly extending driving teeth 19, or recesses, of semicylindrical or other shape. The plates 13 of each pack when engaged by the driving member slide over one another and present at their outer edges a configuration corresponding to the shape of the teeth or recesses of the driving member. Thus the driving torque is transmitted through the teeth 19, but the tension in the driving member and the weight thereof is carried by the side faces 21. Bow springs 23 keep the plates projected when they are not acted on by the teeth 19. The two expanding pulleys are interconnected by links 7 so that one can be expanded while the other is contracted. Instead of the balls 16, rollers or profiled slidable blocks may be used.

Title: Apparatus for and process of coiling rods
IPC: B21C47/26
Filed: 1965-03-16
Abstract: 1,068,301. Rolling; winding and reeling. SOUTHWIRE CO. March 16, 1965 [June 15, 1964], No. 11083/65. Headings B3E and B3M. Apparatus for coiling a rod about an axis comprises means for guiding the rod along a path terminating adjacent to the said axis, and means for supporting convolutes of the coil. Rod 25 from a rolling mill 20 passes through a guide tube 66 supported on a pivoted boom 41, is fed by driven rollers 74, 76 through a guide tube 77 also supported by the boom 41 and is discharged downwardly therefrom to coil into a receptacle 300. The tube 77 discharges at a point near the axis of the coils in the receptacle 300 and as coiling proceeds the boom 41 is lowered by a chain 47 so that the point of discharge moves towards the receptacle and as a consequence the rod is coiled into gradually smaller convolutions. When a first layer is thus coiled in the receptacle spaced rods are inserted in the receptacle above the layer to form a false bottom for the next layer, which rods may be removed after this next layer has been formed. Instead of carrying the tube 77 by a boom 41 the tube may be stationary and have an axially movable sleeve at its discharge end so that the height of the effective discharge may be varied. The hot rod from the mill 20 is cooled in its passage through the guide tube 66 by liquid coolant supply means 32 which direct the coolant towards the direction from which the rod is fed. Means 33, spaced from the means 32 and each including two conically shaped spaced passageways, remove the coolant.

The forward ends of the augers are supported by a pair of earth-slitting blades 2. An endless belt 4 having prongs 5 is arranged above the augers and co-operates with them in elevating the beets. The forward end of the belt is carried by a shaft 7 mounted in adjustable brackets 8, by which its distance from the augers is varied. A weighted chain 11 lies on the lower reach of the belt, the front end of the chain being connected by hangers 13 to the shaft 7. The chain, Figs. 2 and 3, comprises a number of elements each of which is pivoted to the preceding element between its ends, and each of which carries at its rear end a rod 14 supporting a heavy roller 15. The rear end of the chain may be connected by links 17 with arms 16 extending inwardly from the frame 1.

[Also in Division B3] A distributer vessel for a multiple continuous casting plant comprises a vacuum chamber 4 with an inlet pipe for immersion in the melt in a ladle 1 and outlet pipes 5 leading to the moulds 8, and is mounted for tilting about the axes 9, 11, at right angles to one another. Metal is drawn into the evacuated vacuum chamber from the ladle and the chamber is then tilted about the axis 9 so that the plugged outlet pipes 5 are filled. The vacuum is then relieved, the pipes 5 unplugged and the metal automatically flows continuously to the moulds, the pouring rate being controlled by tilting about the axis 9; tilting about the axis 11 enables an increased casting speed to be obtained in one or the other of the two moulds 8. The pouring jet 6 may be screened by a protective gas.

Abstract: 514,626. Counting and integrating mechanism. LEA RECORDER CO., Ltd., and LEA, J. E. April 14, 1938, No. 11445. [Classes 106 (i) and 106 (iv)] In meters for the measurement of coal and other materials adjustment for change of constant of the material is made by means of a helically toothed drum, The intake shaft c of the meter has a pinion d meshing with a pinion f fast on the shaft e of a scroll toothed drum g with which engages a pinion k always in mesh with a long-toothed pinion h' which through a pinion b' drives the counter b. The pinion k is carried by a crank arm j on a shaft h which can be adjusted for engagement with the part of the drum g corresponding to the constant of the material, by screwing the shaft h through its engagement with an arm l, the position set being secured by lock nuts m. Different sets of pinions d, f may be used to give an initial setting according to the standard units. If desired an additional pinion gearing with the long pinion h' may be fitted to drive through a further train of scroll drum and adjusting gear a second counter so that both volume and quantity of material may be read. In another modification a first long drum 29, Fig. 4, may drive a scroll drum 32 and pinions 34, 33 for integration according to a chosen variable.
